Abstract: PURPOSE:To obtain an appropriate monochromatic hard copy irrespective of a kind of a background color by always comparing display data which is read out of a frame buffer with background color data which is set to a window to which a scanning position belongs. CONSTITUTION:A window detecting means 6 detects in which window the present scanning position is contained from positions, sizes and overlap information of windows A, B, C and D stored in a window position register 5 by a position coordinate outputted from a processor MPU 1 and stored in a position register 2. Subsequently, by receiving an output of the window detecting means 6, background color data stored in a background color table 7 is read out, and on the other hand, display data corresponding to the position coordinate in the position register 2 given to a frame buffer 4 is read out. A comparing means 8 compares the display data and the background color data, and '0' of a background part and '1' of a character part are written in an output buffer OB, when a coincidence output is executed, and when a discrepancy output is executed, respectively.

Abstract: PURPOSE:To provide also the function of driving a running wheel by connecting a rotating body for scraping dusts to one side of a rotating shaft extending to both sides of a motor through a belt, and connecting the running wheel to the other side through a belt. CONSTITUTION:A motor 16 and a driving wheel 35 are rotated according to the operating direction in a suction hole body 1. A rotary brush 13 is rotated in the opposite direction to the motor 16 by changing its rotating direction by a frictional wheel (driven side) 20 and a frictional wheel (driving side) 48 in the course. A rotating shaft 30 is extended to both sides of the motor 16, and belts are laid to drive the rotary brush 13 with one belt 49 and the driving wheel 35 with other belts 43, 44. Consequently, although a tensile charge is added to one side of the rotating shaft 30 of the motor 16 through the belt 49 when an excessive load is added to the rotary brush 13, it is well-balanced because the belts 43, 44 for the driving wheel 35 are laid on the other side of the rotating shaft 30, and difficult to form the excessive load to the motor.

Title: Image heating device
Inventor: SAKAI HIROAKI
IPC: G03G15/20
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To stably secure fixing performance at the time of continuous printing independently of the weight of a recording material and the deflection of input voltage by deciding heating condition in accordance with the rate of change of detected temperature when the recording material is held between nips. SOLUTION: Standby temperature is set equal to or lower than fixing allowable temperature by taking advantage of that the fixing performance of initial printing is secured even at lower temperature than at the time of the continuous printing by the heat capacity of a fixing device. Thus, the rate of change of temperature is measured by providing a certain time required to reach fixing temperature from the standby temperature. In the case that controlled temperature is not maintained in spite of changing the turning-on ratio of a heater when the input voltage is lowered at a high-speed machine, the fixing performance is secured by lowering throughput. As to timing for lowering the throughput; the case that the controlled temperature is not attained after printing a specified number of copies based on a VSYNC (image write-in) signal is set as the timing of changeover.

Title: Magnetic fluid seal coupler
Inventor: ARAI MOTOHIRO
IPC: F16J15/40
Filed: 1986-11-13
Abstract: PURPOSE:To detect deterioration of a seal effect of a magnetic fluid prior to leakage of gas by disposing a space for a gas reservoir in the middle of a magnetic fluid seal coupler in the longitudinal direction and providing the first and second magnetic fluid seal areas in such a manner as to sandwich the space therebetween. CONSTITUTION:A gas reservoir space 1 is disposed in the middle of a seal coupler in the longitudinal direction, and magnetic fluid seal areas 3, 6 are provided with the gas reservoir space 1 sandwiched therebetween. Even if the seal effect of a magnetic fluid in the first magnetic fluid seal area 3 is deteriorated by halogen gas, the seal effect of a magnetic fluid in the second magnetic fluid seal area 6 is not deteriorated quite, so that gas including halogen gas flowing out from a gas sealing device is collected in the gas reservoir space 1. Thus the deterioration of a seal effect of the magnetic fluid can be found from a pressure change in the gas reservoir space 1 or the existence/ absence of halogen gas.

Filed: 1987-10-27
Abstract: PURPOSE: To prevent cost increase by renewing a second data to a new data and memorizing it when a first code data discriminates that the second code data is the new data renewed by specified algorithm and unlocking a door. CONSTITUTION: When a magnetic card is inserted into a card reader 2, the card reader 2 reads a data in the card and transmits it to an unlocking control means 3 (3A, 3B). When it matches with a code data, the unlocking control means 3A compares it with a discrimination effective data memorized by a reading data itself, and when it matches with it, the unlocking control means 3A puts on an unlocking solenoid 4 and unlocks a door. When they don't match with each other, the control means 3B checks whether a room number in the data is matched or not, and when it is matched, the reading data judges whether a present effective data is a renewed data renewed by specified algorithm or not.  When it is judged to be as the correct renewed data, the control means 3B renews the effective data to a data read from the card, memorizes the data as a new effective data, actuates the solenoid 4 and unlocks the door.

Title: Device for detecting track-jumping
Inventor: KARITA YOSHIHIRO
IPC: G11B7/085
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To surely detect track-jumping, regardless of noise and the size of a track cross frequency, by detecting a tracking error and comparing a computed dispersion value with a threshold value. SOLUTION: With a tracking servo operating normally, the output of a tracking error detecting part 1 becomes a small value around zero. This is sufficiently smaller than the threshold value of a threshold value comparing part 3 when also computed by a dispersion computing part 2, and is judged to be no track-jumping. In the case of track-jumping, the output of the tracking error detecting part 1 turns to a signal varying in a sine wave shape. Since the value of the dispersion becomes large which is computed in the dispersion computing part 2, this is judged to be track-jumping by the threshold value comparing part 3. In addition, in reproducing a disk whose noise level is high, track-jumping can be detected by judging with the use of the distribution of track-jumping.
